Water Alarm

Timely warning against flooding

Water is vital for humans, but too much of it has an undesirable effect, particularly when it turns up in the wrong places. This is what two Elektor designers discovered after a blocked drain of a combination boiler and a leaking filter of an aquarium. This will quickly suggest the idea of designing a small circuit that will give a clear signal when this type of flooding occurs, in this case with a loud alarm.
